This study aimed to investigate the effect of frozen live food (Daphnia magna) and artificial diets on growth performance, feed conversion ratio and survival of Cyprinus carpio fry reared in 25-liter glass aquaria. Duplicate groups of fry were fed o
n the tested diets three times a day to satiation for 21 days.
The results revealed that the growth rates (weight gain, % weight gain) were significantly (P<0.05) affected by the used diets. Fry fed on the frozen live food showed the worst growth rates, even their feed conversion ratio expressed the lowest value compared with the results obtained from fry fed on the artificial diets, although survival was not significantly (P>0.05) affected with the different diets. No significant differences (P>0.05) were noticed in the results obtained from fry fed on the different artificial diets.
The study was conducted at the Breeding and fish diseases
Laboratory - College of Veterinary Medicine were used drug
substance ivermectin concentration of 1% - 50 μg/ kg on the
normal Carps.
Brucellosis is an endemic zoonosis in Syria, affecting large numbers of
animals and an increasing number of humans. Brucella is an intracellular
pathogen capable of infecting animals and humans. The aim of this study was
to develop a polymerase ch
ain reaction (PCR) protocol for the detection of
Brucella melitensis in artificially contaminated cheese.
This research aimed to study the effect of adding different rates of lysine on the weight and
growth of common carp fingerlings. The experiment was carried out in the laboratory for 4
months using eight glass containers (40 liters each) with four t
reatments (L0 no Lysine
addition, L1 (2%), L2 (3%), L3(4%) of the total weight of diet. Eight common carp
fingerlings (average of tall 7.5cm ± 0.05 and average of weight 12.25g ± 0.57) were
cultured in each container with Oxygen pumps and filters.
Results showed by growth rate, absolute growth rate, specific growth rate and food
conversion ratio (FCR) that the treatment L1 (2% lysine) was significantly the best
comparing to the other treatments, where FCR was (2.2) and the specific growth ratio was
(0.28 %)
Fish farming using earthen ponds is considered one of the most commonly-used
ways in Syria. It is one of the important resources of fish production in the country .In the
last years ,the importance of producing fish to meet the needs of Syrian citi
zensfor animal
protein has increased ,due to the shortage of sources and the increasing prices of animal
products on one hand , and the greatly growing population on the other.
The research aims to achieve the following objectives:
1 -Calculating the Production costs for all production processes contained in stages
farming fish in ponds and carry out a study and analysis of these costs account.
2- The economic evaluation t of farming fish using earthen ponds in Latakia through
the expense of some economic analysis indicators.
Through research we came to the following results:
1-The net profit achieved was 102847,3 SYP/1000m2
2- The total production costs was147952,7SYP/1000m2
3-The farm Production efficiency reached 1,97and the economic efficiency 1.69
4-The profitability index as related to production costs amounted to 81.83 % and as
related to the invested capital amounted to 20.65%.
